The primary goal of writing this book is to present the complex questions in a simple and accessible manner, which are commonly asked in competitive examinations such as M.Sc., Ph.D., Assistant Professor, SRF, JRF, NET, and others. Due to the vast amount of information required on various subjects in Plant Breeding and Genetics, students are often reliant on a variety of books, literature, monographs, research papers, and other materials. The book Genetics and Plant Breeding for Competitive Examinations has been written to cover all the courses offered in both undergraduate and postgraduate programs, and it includes a large number of objective-type questions that have been formulated chapter-wise, which required considerable efforts.
